Does spinning a diametrally magnetised rod magnet increase its magnetic field, like a Halbach Array?

A halbach array augments the magnetic field on one side and cancels it out the other. Moving along a linear Halbach array or positioned on the circumference of a spinning rotary halbach array (see ...

Construction of Halbach Array

Would it be feasible to construct a Halbach cylinder from a cylindrical bird cage of diametrically polarized permanent magnetic discs or rods? If so, would it be possible to stack and bond discs? I am ...

How symmetric Halbach array can produce asymmetric magnetic field?

I don't understand. If I look at a picture of Halbach array I see it is apparently symmetric. At least both pairs of opposite sides are. Then how can it have "weak" and "strong" opposite sides?

Halbach array magnetic polarity

Above is a Halbach array arrangement of magnets that has its field flux concentrated on one side and cancelled out on the other. Now I wish to know the polarity (if there exist any) of the side with ...

Electromagnet Halbach arrays

Could a set of electromagnets be arranged in a Halbach array? If so, what would happen if only half were turned on? And if polarity were reversed? I have researched thoroughly, and I found a post on ...

When is a configuration a Halbach configuration?

I just started reading about Halbach arrays. What I don't understand, is how do you know you have a magnet configuration which is Halbach? Is there a unique formula for the magnetic directions which ...

Halbach array and levitation

Full disclosure: I am a total novice when it comes to physics apart from being very curious and basic physics classes at school level (long long ago). Using 16 mm diameter disc magnets. I am ...

How to create a strong magnetic field using permanent magnets

I would like to build a strong magnet using 100 6"x4"x1" permanent magnet blocks. What is the best way to place them so I get the strongest magnetic field? (Should I stack 2 rows of 50 ...

Magnetic monopoles in Halbach array?

I am a bit confused by the description of Halbach arrays. It is said that the line of magnets aligned in a certain way results in cancellation of magnetic field on one side of the array, and ...

Induction and Halbach array

I have recently studied and tried to understand the concept of the Inductrack, a form of magnetic levitation. In the following link they present three different ways to construct the track: http://...
